Watch Free Online HD Moviesjoy. Mr. Krása’s not your ordinary country farmer – he’s also a DIY-er and amateur inventor. When reporters come to interview him one day while in the middle of mowing his lawn and gathering chicken eggs, he introduces them to his inventions: a lawnmower, a cooling oven, and most notably his singing robot Karel, who’s managed to take over the world with his infectious songs. A film grotesque and mockumentary about the origin of a Czech music legend.
